The optical resolutions of various alcohols as phenylcarbamates were examined by HPLC on chiral stationary phases derived from sixteen cellulose tris(phenylcarbamate) derivatives. The optical resolving power of chiral stationary phases was greatly influenced by substituents on the phenyl groups of the cellulose derivatives. Also, cellulose tris(3,5-dimethylphenylcarbamate) could very efficiently resolve
通过 HPLC 在源自十六种三(苯基氨基甲酸酯)纤维素衍生物的手性固定相上检测各种醇作为苯基氨基甲酸酯的光学拆分。手性固定相的光学分辨率受纤维素衍生物苯基上的取代基影响很大。此外,纤维素三(3,5-二甲基苯基氨基甲酸酯)可以非常有效地分离许多外消旋苯基氨基甲酸酯,包括 2-丁醇、3-丁烯-2-醇和 1-苯基乙醇的氨基甲酸酯。在苯基上具有给电子取代基的外消旋苯基氨基甲酸酯比具有吸电子取代基的那些更好地分离。大多数醇类的苯甲酸盐没有氨基甲酸盐那样有效地分解。
